Very durable and fits very nice (whereas 90% don't fit my face very well). Highly tinted and less transparency. Only thing is that the tint starts to fade away once you use normal clothes (tshirt for instance) to wipe the dirt off. Highly recommended for the price-value!
I've been using them for to short time, but it's one of the better models I've ever used, they've brought me protection against the sun and they're so comfortable, I totally recommend this product, besides, given their quality, they're pretty cheap. God bless you all, keep making sunglasses like these.
